(Vp) along the cable length. Accurate positioning of the cursor is also required. **Specifications are subject to change without notice. Fault Mapper Pro Model CA7027 ® GlobalTestSupply www.
Accuracy The CA7027 is able to measure distances to faults and cable lengths to an accuracy of ±1%. This measurement accuracy is based on the correct value of Vp being used for the cable under test, and homogeneity of the Vp along the cable length.
When locating faults with the Fault Mapper Pro the cursor should be positioned at the beginning of the feature on ® the cable waveform as shown below. Vp=72% Z=100Ω 621ft Fault Mapper Pro Model CA7027 ® GlobalTestSupply www. .com uality Products Online at: sales@GlobalTestSupp...

Tone Generator The Fault Mapper Pro may also be used as a tone generator, to trace ® and identify cables and wires. The user will need a cable tone tracer, such as the AEMC Tone Receiver/Cable Tracer Model TR03 (Cat. #2127.76) or equivalent. Pressing the button will inject a warbling (oscillating) tone into the TDR / cable or link under test. When set, the following will be displayed: * * * * * * * * * * * * * * * * * * *...

To determine the distance to an event, position the cursor at the beginning of the event and read off the distance as shown below. Vp=72% Z=100Ω 413ft On the fault curve shown in the previous two screens, a low impedance event occurs at 210 ft, shown by a downward spike on the curve, and a high impedance event occurs at 413 ft. The open end of the cable is shown as a large positive spike This is used to determine the end (length) of the cable.
